Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To execute a test at a high speed and with excellent accuracy by executing the test by giving a pulse-shaped voltage as a bias voltage to a device (DUT) to be measured. SOLUTION: A network analyzer 11 controls a voltage-current generator 31 on a program basis by a built-in controller and executes an automated test of high frequency IC as DUT 20, for instance. An output voltage of the voltage- current generator 31 is generated in the shape of a pulse for each measuring point by a synchronous signal and impressed as a bias voltage on the DUT 20. The output voltage of the voltage-current generator 31 is varied and output power characteristics of the DUT 20 are plotted sequentially by an arithmetic processing and displayed on a screen. In this way, the bias voltage is impressed in the shape of the pulse on the DUT 20 and the time for fetching test data is made fast.  Since the DUT 20 causes no temperature rise during the time when the pulse is not generated and, therefore, causes no change in the characteristics according to this constitution, the test can be executed at a high speed and with excellent accuracy.
